The name is part of a site configuration setting, so only system administrators can change it.

When zh_TW was added to Tatoeba, because we were not sure what was the best name to use, to keep it safe we used the same name as what is used on https://zh.wikipedia.org/. You can check the discussion that happened at that time: https://github.com/Tatoeba/tatoeba2/issues/2672

You are welcome to share your expertise on this topic.

Here's more about the change request:

the language name is better to be shown as "中文 (台灣)", also, the language name for Chinese (China) is better to be "中文 (中国)" (or "中文 (中国大陆)" for geopolitical reasons). We should not use the current （大陆简体） and （臺灣正體） because it's solely a Wikipedia mechanism, not for interfaces in general. The most common way to show interface language options are the way I listed above. Android, iOS, Windows, etc all have the two variations of languages shown like that. I'm strongly recommend that we should change them.

there's also another solution completely avoiding geopolitical problems: rename Chinese (Taiwan) into Chinese (Traditional), i.e. 中文 (繁體); and rename Chinese (China) into Chinese (Simplified), i.e. 中文 (简体). I recommend this more.

Awesome, thank you very much! I really appreciate your translation effort, and all your contributions in general by the way. I will apply the Chinese translation to tatoeba.org this week.
